Abstract (en)
The invention refers to a driving wheel for car engines or the like, incorporating a gear wheel, which is intended to cooperate with a cogged belt, and a pulley (9) attached to one side of the gear wheel and arrested to this. The invention is characterized therein that the gear wheel is moulded from a plastic or similar material having a high coefficient of thermal expansion and that a helix (3) of steel or another material with desired coefficient of thermal expansion is embedded in the gear rim (1) of the wheel radially inside the cogs (2), whereby the helix (3) has such a strength and dimension that it determines the thermal expansion properties of the gear rim (1).
